Your retina uses a form of vitamin A to detect light. A real shortage causes night blindness, which is why this vitamin always appears in eye formulas.

Retina Clear

Most people who eat vegetables, dairy and eggs are not short of it. Beta carotene is the plant version your body converts as needed, so it is gentler than pre-formed retinol.

Retina Clear

Large trials found that high-dose beta carotene supplements raised lung cancer risk in smokers, so people who smoke should check with a doctor first.

In Retina Clear: 450 mcg RAE (50% DV). Compare this with the amounts in research before deciding whether the capsule fits your goals.
